In this way, different noise reduction door forms can be obtained by changing different mounting positions and installation manners of the fan-shaped structural members 202 on the door panel 203, which can meet different noise reduction effects and air duct resistance requirements. For example, the position of the sector structure member 202 in the installation mode (streamline type installation method) of FIG. 1 can be changed to the left and right, so that the installation effect of the noise reduction door is as shown in FIG. 2, that is, the structure diagram of another noise reduction door (maze) Type of installation).

Next, the manner in which the T-shaped structural member 201, the sector-shaped structural member 202, and the door panel 203 are connected will be described.

A connectable manner is as follows: for the connection of the T-shaped structural member 201 and the sector-shaped structural member 202 and the door panel 203 in FIGS. 1 and 2, as shown in FIG. 3, the door panel 203 and the T-shaped for the noise reduction door Schematic diagram of the assembly of the structural member 201 or the sector structure member 202. The door panel 203 includes a sleeve member 401, and the T-shaped structural member 201 and the sector-shaped structural member 202 respectively include a cylindrical member 402, the door panel 203 and the T-shaped structural member 201, the door panel 203 and the The sector members 202 are each connected by the sleeve member 401 and the cylindrical member 402, the diameter of the cylindrical member 402 being smaller than the diameter of the sleeve member 401.

Thus, the T-shaped structural member 201 or the sector-shaped structural member 202 can be lifted up until the lower edge of the cylindrical member 402 is higher than the upper edge of the sleeve member 401, and the T-shaped structural member 201 or the sector-shaped structural member 202 is brought close to the door panel 203. Until the axis of the cylindrical member 402 is aligned with the axis of the sleeve member 401, and then the T-shaped structural member 201 or the sector-shaped structural member 202 is lowered, the T-shaped structural member 201 or the sector-shaped structural member 202 can be mounted on the door panel 203. .

The material of the T-shaped structural member 201 and the scalloped structural member 202 may be a sound absorbing material, such as a porous fibrous material, which is not limited herein.

It can be understood that another connectable manner may be that the door panel 203 includes a cylindrical member 402, and the T-shaped structural member 201 and the sector-shaped structural member 202 respectively include a sleeve member 401, the door panel 203 and the T-shaped structural member 201, the door panel 203 and the sector-shaped structural member 202 are both connected by the sleeve member 401 and the cylindrical member 402, the cylindrical member 402 having a smaller diameter than the sleeve member The diameter of 401. Thus, when the connection is installed, the door panel 203 can be lifted, and the cylindrical member 402 on the door panel 203 can be inserted into the T-shaped structural member 201 or the cylindrical member 402 of the sector-shaped structural member 202.

In order to allow the T-shaped structural member 201 and the sector-shaped structural member 202 to be stably mounted on the door panel 203, the inner side wall of the sleeve member 401 is provided with a recess, the outer side wall of the cylindrical member 402 is provided with a spherical member and a spring 403, and the cylindrical member 402 Hollow, the spherical member 404 is coupled to one end of the spring 403, the other end of the spring 403 is fixed to an inner side wall of the cylindrical member 402, and a portion of the spherical member 404 is embedded in the recess. That is, a portion of the spherical member 404 is projected out of the wall of the cylindrical member.

Further, after the production of the components of the two sets of noise reduction doors is completed using the same mold, a noise reduction gate combination is obtained, which can reduce the manufacturing cost.

Further, after the noise reduction door combination is obtained, according to different resistance requirements and noise reduction requirements of the cabinet system, the installation position and installation manner of the sector structure member 202 can be changed. Different noise reduction door forms meet the needs of different noise reduction effects and air duct resistance.

The effect diagram of the noise reduction door combination and the cabinet installation can be as shown in FIG. 5 to FIG. 8 (assuming that the fan 502 of the cabinet 501 is at the air outlet, that is, at the rear door), wherein the arrow direction indicates the wind direction.

Specifically, as shown in FIG. 5, the noise reduction door at the air inlet (at the front door) and the noise reduction gate flow path at the air outlet are both streamlined and have low resistance, and are suitable for occasions where the wind resistance of the noise reduction door is small;

As shown in Fig. 6, the noise reduction door at the air inlet and the noise reduction gate flow channel at the air outlet are all labyrinth-shaped, and the noise reduction effect is large, which is suitable for the occasion where the noise reduction effect of the noise reduction door is obvious;

As shown in Fig. 7, the noise reduction gate flow passage at the air inlet is a labyrinth shape, and the noise reduction gate flow passage at the air outlet is streamlined, which is suitable for occasions with high noise reduction effect and low wind resistance;

As shown in Fig. 8, the noise reduction gate flow passage at the air inlet is streamlined, and the noise reduction gate flow passage at the air outlet is a labyrinth type, which is suitable for occasions with low wind resistance and low noise reduction effect.

Since the wind direction at the air outlet is diffused to both sides, when the operator operates at the back door, the airflow and noise are not directly facing the operator, and the operation experience is good.

When the cabinet with the noise reduction door of the present invention is combined, a noise reduction door needs to be opened. If only one person is required to maintain, the angle of opening the door may be 90°. At this time, one end of the T-shaped structural member 201 is closest to the nearest portion. The connection between one end of the door panel 203 and the door panel 203 may be 45°, and the effect diagram after opening the door may be as shown in FIG. 9. Of course, it can also be less than 45°.

If two people need to maintain, when the door opening angle can reach 120° or other angles, the fan-shaped structural member on the right side of the left noise reduction door can be rotated and moved, so that the angle of the right noise reduction door can be opened 120° or Other angles, as shown in Figure 10, are convenient for two people to maintain.

When the noise reduction door is packaged and transported, the four parts of the noise reduction door can be disassembled and packaged, which can reduce the packaging volume and save transportation costs. As shown in Fig. 11, the original two packages (left side schematic) are merged into one. The package (right side view) reduces the package size.
